Dear members,
I have the following code:
> tryCatch(function() print("fred"), error = function(e)
sum(1:3), finally = sum(1:3))
function() print("fred")
The expected output from the tryCatch call should be to print "fred"
to the console, and exit, but as seen above, it is outputting
function() print("fred")
Can you people please shed some light on what is happening?
thanking you,
Yours sincerely,
AKSHAY M KULKARNI

You have simple defined the function -- you have not called/executed it. This defines and calls it:> tryCatch({function() print("fred")}(), error = function(e) sum(1:3),finally = sum(1:3)) [1] "fred" Cheers, Bert> and exit, but as seen above, it is outputting > function() print("fred") > > Can you people please shed some light on what is happening? > > thanking you, > Yours sincerely, > AKSHAY M KULKARNI > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help at r-project.org mailing list -- To UNSUBSCRIBE and more, see > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >[[alternative HTML version deleted]]
You defined a function. You did not call the function. tryCatch returned the
object you defined. So the interactive console printed the object returned.
Invoking the "function" function does not call the defined function
for you. Try:
tryCatch((function() print("fred"))(), error = function(e) sum(1:3),
finally = sum(1:3))
